i am going to Alaska i am going to mostly do deep sea fishing, but there are some streams and it is in a cove and there last time i went there was someone fishing for sea bass or rockfish in the cove with spinning gear. what type of flies are good for rock fish or sea bass in Alaska?

If you are fishing for Rock Fish I am afraid a fly rod is not the best tool. Rock fish can be very deep. You would be better off targeting Halibut but not with a fly rod. The commercial harvesting of rock fish was allowed to damage the fishery before it was determined that rock fish are slow to mature. If you want to fly fish on your trip you should try the streams you mentioned.

The Sockeye's will probably be running then, my personal favorite on the fly rod, but very picky about taking a fly. Depending on the area, Chinook can also be caught then. And yes, the Dolly are in most of the coves with streams that have salmon fry coming out of them right now. I was hooking one on every cast today. I've never fished down there, but I hear there are tons of small streams around there with trout, so I'm sure you can find something great to catch when your done fishing in the deep water!

i am going up on June 21st. I would fish after we got our limit of salmon/halibut out at sea. it is on an island called elfin cove.

Great. Elfin Cove is a fine village with great fishing. Coincidentally, we are flying in to a friend's place over on Lemesurier Island (between Chichagof Island where EC is and Glacier Bay) on Sat the 28th.
